Crate mdstitch 

Streaming markdown preprocessor that auto-completes incomplete syntax.

Runs on raw markdown strings before the pulldown-cmark parser, detecting and closing unterminated formatting markers so content renders correctly during token-by-token streaming.

Modules

priority

Built-in handler priorities.

Structs

CodeBlockRanges

Pre-computed ranges of text that are inside code blocks, inline code spans, or math blocks. Used to skip these regions in emphasis/katex handlers without redundant O(n) scans.

StitchOptions

Configuration options for the stitch function.

Enums

LinkMode

How to handle incomplete links.

TextDirection

Text direction: left-to-right or right-to-left.

Traits

StitchHandler

A custom handler that transforms text during the stitch pipeline.

Functions

detect_text_direction

Detects text direction using the “first strong character” algorithm.

has_incomplete_code_fence

Returns true if the markdown text has an unclosed code fence.

has_table

Returns true if the markdown text contains a table delimiter row.

is_inside_code_block

Returns true if the position is inside a fenced code block (between ``` markers) or an inline code span (between ` markers).

is_within_link_or_image_url

Returns true if position is inside the URL portion of a link/image ](url).

is_within_math_block

Returns true if position is inside a math block ($ or $$).

is_word_char

Returns true if ch is a Unicode letter, digit, or underscore. Matches the TS isWordChar / [\p{L}\p{N}_].

normalize_html_indentation

Strips excessive indentation (4+ spaces/tabs) from lines that start HTML blocks.

preprocess_custom_tags

Preprocesses custom HTML tags to prevent blank lines within them from causing CommonMark to split the block.

preprocess_literal_tag_content

Escapes markdown metacharacters inside specified HTML tags so their content renders as plain text.

stitch

Preprocesses streaming markdown text, auto-completing any incomplete syntax.
